Configuring Service Mirroring with CLI
Page 1310 7750 SR OS Services Guide
Mirror Configuration Overview
7750 SR mirroring can be organized in the following logical entities:
•The mirror source is defined as the location where ingress or egress traffic specific to a
port, SAP, MAC or IP filter, or ingress label or a particular service is to be mirrored
(copied). The original frames are not altered or affected in any way.
• An SDP is used to define the mirror destination on the source router to point to a remote
destination (another router).
• A SAP is defined in local and remote mirror services as the mirror destination to where
the mirrored packets are sent.
Defining Mirrored Traffic
In some scenarios, like using VPN services or when multiple services are configured on the same
port, specifying the port does not provide sufficient resolution to separate traffic. In Alcatel-
Lucent’s implementation of mirroring, multiple source mirroring parameters can be specified to
further identify traffic.
Mirroring of packets matching specific filter entries in an IP or MAC filter can be applied to refine
what traffic is mirrored to flows of traffic within a service. The IP criteria can be combinations of:
• Source IP address/mask
• Destination IP address/mask
• IP Protocol value
• Source port value/range (for example, UDP or TCP port)
• Destination port value/range (for example, UDP or TCP port)
• DiffServ Code Point (DSCP) value
• IP fragments
• IP option value/mask
• Single or multiple IP option fields present
• IP option fields present
• TCP ACK set/reset
• TCP SYN set/reset
•ICMP code
• ICMP type
• SAP ingress/egress labels
